The CM50 MIDI Locator - product no longer available

Two machine autolocator with control for one Master and one Slave

Parallel interface for Analogue Multitracks as a Master. Enables a vast range of older multitracks to operate in a modern digitally controlled studio.

MIDI Machine Control (MMC) for Digital Multitrack as a Slave

RS232 IBM-PC Serial Port. An optional set-up program running under Windows is available.

28 Cue Points with permanent storage. Entry ‘on the fly’ or via the keypad. Trimmable by frames using +/- keys.

A loop may be set up with either ‘Return or Start’ or ‘Continuous’ modes. Drop in point, Drop out point, Pre-roll, Rehersal modes are all selectable.

Offset between Master and Slave may be selected on the keypad or trimmable using the +/- keys.

Upwards of 40 machine interfaces supplied.

All parameters my be set up on the integral keypad or on a PC connected vis the serial port. All storage is in the CM50 internal memory which is retained when power is removed.

The CM50 MIDI Locator, based on the earlier CM50 and I-Con 16 autolocators, includes many features only previously available on our top of the range products. It is designed to operate as a remote control for an analogue multitrack with a slave port enabling control of one of a growing number of MIDI Machine Control (MMC) or 9-Pin controlled tape machines. Currently we only have an interface for the Tascam DA-88.

All interfaces are based on the already established Applied Microsystems list which currently stands at around 40 machines. What’s more, we have retained the same method of storage in that, when you purchase one of our controls products, you purchase the whole interface library - all that is needed is the relevant cable which we would normally supply from our stock. However, some customers provide their own cables as we supply full documentation on request.

The CM50 MIDI Locator is primarily an autolocator with a very similar appearance to our CM50 which it supersedes. In order to sell at a competitive price, we have reduced the component count by using state-of-the-art chip trechnology. We have added MIDI, 9-Pin and and RS232 ports to the existing parallel remote control to enable it to lock a DA-88 to a conventional multitrack.

PORTS: There is one parallel control port using relay output and two independent serial ports: one serial port is switchable between MMC (MIDI - opto-isolated 31.25Kbaud) or 9-Pin (RS422 38.2Kbaud), the other is an RS232 IBM-PC port running at 9.6Kbaud.

OUTBOARD CONTROL: We have provided a ‘free’ change-over relay for triggering external events from cue points, for example. The use of this relay is limited only by your imagination! The contacts are accessible on the 25 way ‘D’ connector. There are also pins carrying event-triggered serial data (SC50 decoder required).

Combined MIDI and 9-Pin port on 9 way ‘D’ socket

Parallel Port on 25 way ‘D’ Connector. Included 5 voltage-free relays for transport control + ‘User’ free relay. Other signals on the port are: Tach, direction, play and stop status from the transport. Also serial event data, clock and strobe for use with external decoder.

Power Requiremants: 15-30vdc at 75ma - this is such a small load that it is normally taken from the master tape machine via the 25 way interface connector.
